GetDC Function: Windows API for Device Context Retrieval

GetDC is a Windows API function used to retrieve a handle to a device context (DC) for a specified window or device. A DC is a structure that defines a set of graphic objects and their associated attributes, and provides a way to draw graphics on a device such as a screen or printer. The GetDC function is typically used by applications to obtain a DC for drawing graphics on a window or device, and to release the DC when drawing is complete. The function takes a window handle or device handle as its parameter, and returns a handle to the associated DC.
